The TC350 Plus laminates are ceramic filled PTFE-based woven glass reinforced composite materials with a thermal conductivity of 1.24W/mK. They have low z-axis CTE (38ppm/°C) for excellent plated through hole reliability, a low loss tangent of 0.0017 at 10 GHz to enable low loss designs, low moisture absorption of 0.05% to ensure stable performance in a range of operating environments, high dielectric strength of 650 V/mil to ensure good z-axis insulation between conductor layers, and UL 94 V-0 flammability performance to enable the use of the material in commercial applications.
These laminates are available with a smooth (Rq= 1.0µm) electrodeposited copper foil cladding to reduce insertion loss and RF heating of conductors within the circuit. TC350 Plus laminates are available in various thicknesses options from 0.010” to 0.060” to address higher power design needs. They are ideally suited for a range of applications including Amplifiers, Combiners, Power Dividers, Couplers, and Filters. Applicable markets range from Commercial and Consumer to Defense and Aerospace.
